Abstract

PURPOSE:To actuate an engine of a simple structure, by setting a piston in a reciprocating motion by the use of repulsive force of a superconductive plate. CONSTITUTION:A superconductive engine is composed of a cylinder 1, a crankshaft 2, a crank pin 3, a superconductive disk 4, a superconductive ring 5, and a piston 6. When the crank pin 3 is at a top dead center 7, the superconductive disk 4 is kept in a superconducting state for a short time and the piston 6 made of a magnet is pushed down by Meissner effect. The crank pin 3 passes the right side of the crankshaft 2 and approaches a bottom dead center to keep the superconductive ring 5 in a superconducting state for a short time and by Meissner effect the piston 6 is pushed up. The crank pin 3 passes the left side of the crankshaft 2 and returns to the top dead center 7. By alternately switching this superconducting state with the normal state, the piston 6 is set in a reciprocating motion.

Description

Detailed Description of the Invention: Industrial Field of Application The present invention utilizes the repulsive force of a superconducting material in a superconducting state with a magnet due to the Meissner effect to obtain power.
``This is about the L engine.

BACKGROUND OF THE INVENTION In recent years, engines used in automobiles, ships, etc. have become increasingly indispensable as means of transportation or recreation.

An example of the conventional engine mentioned above will be described below with reference to the drawings. Figures 2 and 3.

FIGS. 4 and 5 are cross-sectional views of a four-stroke gasoline engine, which is the most common automotive engine.

In FIG. 2, 11 is a cylinder head, and 12 is an intake port, which is an inlet for a mixture of air and gasoline. 13 is an exhaust port, 15 is a cylinder, and the piston 14 is the cylinder 15
slide inside. 16 is a crankshaft that transmits the power generated within the cylinder.

17 is a crank pin.

The operation of the four-stroke gasoline engine configured as described above will be described below.

In FIG. 2, the intake port 12 first opens, the exhaust port 13 closes, and the piston begins to descend. The negative pressure generated within the cylinder due to the downward movement of the piston causes the air-fuel mixture to flow into the cylinder from the suction port.

When the crank pin 17 rotates on the right side of the crankshaft 16 and reaches 2A, which corresponds to the bottom dead center, the intake port 12 closes.

The above is the first step. In FIG. 3, the crank pin 17 that has passed the bottom dead center rotates on the left side of the crankshaft 16 and rises, and the air-fuel mixture sucked in in the first step is compressed by the piston 14.

The above is the second step. In FIG. 4, when the crank pin 17 reaches top dead center B, an electric spark is emitted, causing the compressed air-fuel mixture to explode. The explosive gas expands and pushes down the piston 14. This is the third step. In FIG. 5, the exhaust port 13 is opened and the combustion gases are pushed by a piston moving from bottom to top and exhausted into the atmosphere. The above four steps are called one cycle. - Power is obtained by running this cycle in rapid succession.

Problems to be Solved by the Invention However, the above configuration is uneconomical because fuel such as gasoline cannot be used. Furthermore, the emitted combustion gas is harmful to the human body and causes air pollution. Furthermore, it requires precise mechanisms and controls such as the optimal mixture ratio and intake amount of gasoline, and ignition timing, and the manufacturing process is complicated and costly.

In view of the above problems, the present invention provides a superconducting engine that does not require fuel such as gasoline and has a simple structure in which a piston is reciprocated using the repulsive force of a superconducting plate, and that can obtain power through operation. be.

Means for Solving the Problems In order to solve the above problems, the superconducting engine of the present invention includes:
An engine in which a piston made of a magnet reciprocates between top dead center and bottom dead center has a superconducting disk in the upper part of the cylinder in the engine, and a superconducting ring installed in a part outside the movable range of the lower crankshaft. However, by switching the superconducting disk and the superconducting ring between a superconducting state and a normal state, the piston reciprocates and power can be obtained via the crankshaft.

Operation The present invention is safe because it does not require fuel such as gasoline and therefore does not generate harmful gases such as fuel gas. In addition, since the repulsive force of the superconducting plate provided in the cylinder is used to cause the piston to reciprocate, power can be obtained with a simple structure and operation.

EXAMPLE Hereinafter, a superconducting engine according to an example of the present invention will be described with reference to the drawings. FIG. 1 shows a sectional view of a superconducting engine in a first embodiment of the present invention.

In FIG. 1, 1 is a cylinder, 2 is a crankshaft, 3 is a crank pin, 4 is a superconducting disk, and 5 is a superconducting ring, which are fixed within the cylinder. 6 is a piston that reciprocates within the cylinder.

The superconducting engine configured as above will be explained with reference to the drawings. When the crank pin 3 is at the top dead center 7, the superconducting disk 4 is brought into a superconducting state for a short time, and the piston 6 made of a magnet is caused by the Meissner effect.
Press down. The crank pin 3 passes along the right side of the crankshaft 2 and approaches the bottom dead center 8. At this time, the superconducting ring is brought into a superconducting state for a short period of time, and the piston 6 is pushed up by the Meissner effect. The crank pin 3 passes through the left side of the crankshaft 2 and returns to the top dead center 7.

As described above, a superconducting material is placed on the upper surface of the cylinder and near the bottom dead center, and the superconducting state and normal state are alternately switched, and the piston made of a magnet is pushed by the repulsive force of the Meissner effect that is generated when the cylinder is in the superconducting state. Exercise. At this time, power can be transmitted to the outside via the crankshaft, for example, to rotate the wheels of a car.

In the above examples, as the superconductor material, for example, a so-called room temperature superconductor is used, or a material whose superconducting critical temperature is between room temperature and the boiling point of liquid nitrogen is used and cooled with liquid nitrogen (not shown). Alternatively, a material with a superconducting critical temperature below the boiling point of the liquid chamber □ element may be used and cooled with liquid helium (not shown). Examples of room-temperature superconductors include strontium (Sr), barium (Ba), yttrium (Y), and copper (Cu).
There is a ceramic oxide containing 1:l:l:3, respectively. As an example of the manufacturing method, a predetermined amount of each powder of SrCO2 and B a CO3-Y 203°CuO is mixed as a starting material, pulverized, and heated in air for 90°C.
Bake at 20°C for 5 hours. This firing and crushing process is repeated three times to improve homogeneity. After cold compression molding the mixed powder treated in this way, it was placed in air at 1000°C for 5
Manufactured by baking for a period of time and slowly cooling.

Effects of the Invention As described above, the effects of the present invention are such that, in an engine in which a piston made of a magnet reciprocates between top dead center and bottom dead center, a superconducting disk is provided in the upper part of the cylinder in the engine, and a crank part is provided in the lower part. It has a superconducting ring installed outside the movable range of the shaft, and by switching the superconducting disk and the superconducting ring between a superconducting state and a normal state, the piston reciprocates and generates power via the crankshaft. can be obtained. At this time, since no fuel is used unlike a gasoline engine, the cost is low and there is no need to worry about atmospheric pollution caused by combustion gas. In addition, there is no vibration caused by the explosion of fuel, and there is no harm to the environment.
